摘要:

在酸性气藏中,元素硫的沉积会减小气体的流动空间,其进一步的沉积会堵塞气体的流通通道,导致气井产量降低。为加强对高含硫气藏地层中单质硫沉积规律的认识,进行了以下理论研究:考虑元素硫吸附效应,建立一套系统的高含硫气藏元素硫地层沉积预测模型,并利用该模型对某油田实例进行计算;在地层水体存在的条件下,对硫沉积带来的影响。结果表明:当硫吸附效应或者地层水体存在时都会进一步加大硫沉积量,并且随着时间的推移,影响更加明显;在离气井较远的地带,硫吸附效应的影响更强。在理论研究的基础之上,进行了单质硫的聚集实验及其在岩石空隙中的分布规律实验。通过对实验结果的分析,硫的聚集是从纳米级的单质硫晶体聚集形成面状单质硫,再逐渐形成层状似的单质硫;单质硫在孔隙中的分布规律为:孔隙越大,硫沉积量越大。

Abstract:

In acidic gas reservoirs,the deposition of elemental sulfur will reduce the space for gas.Further deposits can clog the gas flow channel,resulting in lower gas production.In order to strengthen the law of sulfur deposition in the gas reservoirs with high sulfur content,the following theoretical study was conducted.Considering the existence of sulfur adsorption,the prediction models of sulfur deposition was done;the influence of presence of formation water to sulfur deposition was discussed.The model was calculated for example.The results show that the presence of sulfur adsorption or presence of formation water will further increase the amount of sulfur deposition.Over time,this trend is more evident.The farther to the gas wells,the stronger impact of the former factor.Based on theoretical research,the accumulation rules and deposition laws of elemental sulfur in cores were studied by experience.Through the analysis of experimental results,aggregation of sulfur is from sulfur crystals to form planar elemental sulfur,and then gradually form layered sulfur.Sulfur distribution in the pores is the larger the pore space,the more the amount of accumulated sulfur.
